Light Reflection and Light Refraction

How do light rays reflect and refract? Does light travel at different speeds in different mediums? This lesson reviews how light waves can be reflected and refracted, and how light waves can change speed when being transmitted from one medium to another. Snell's Law is examined in detail, as are the properties of light waves in general, such as speed, frequency and wavelength. An exploration of mirrors (for light reflection) and lenses (for light refraction) are included, as are prisms which exhibit light dispersion and internal reflection. Lastly, examples of how light reflection and light refraction are used in modern devices and technologies are provided.
